'['o allzu/tom it may conce/"u,"

Be it known that I, FRANois il. MURPHY, citizen of the United States', residing at Jer sey'City, in the county of Hudson and State of New Jersey, hnve invented eeitoiii new und uselul v linproveinents 1n yphonographl-VIoi-ns, oi which the 'following is u spor-ihmlion.

'llie present 'invention hns for its Obwt tuprovide miiinproved forni of horn of t seclioniil type, designed most especially for sound reproihiring,r nnichiiies, such ns ilioin'igrephs', although adapted for use wliere sound is to be amplified.

. The invention i'elntes to Vthe menus for coiinecting the sertions of thc horn. whereby olose, iiin, substantiel und noot joints result.

l niid which joints strengthen, lnsoe nud stiffen the horn in the direction of its length, while nt the seine time admittingol the structure being light and chesp.

For u full understanding oi the invention and the merits thereof nnd also to enquire e knowledge of the details of Construction and the menus for effecting the result, reference is to be had to the following description and eeconipenyin drawings.

Wlii e the invention muy be adapted to different forms und conditions by changes in the structure nud minor details without de porting from the spirit or essential features thereof, still the preferred einbodipient is shown in the iii-.ooinpnnying drawings, in which:

Figure 1 is e. perspective view ci" a. hoi-ii embodyingr the invention end eoniln'ising n body portion end s. base; Fig. 3 is n longitiv dinalseotioii of the upper viortious of the coupling end portions of the iody und linee, showingr the pnl-ts on s larger seele. Fig. Pi is a view of the inner side of the joint formed between adjacent sections; Fig. 4 is a view of the parte illustrated in Fig. 3, ne seen from the outer side; Fig. 5 is a, seotion on the line x--at of Fig. 3; Fig. 6 is a section on the line of Fig. 3; Fig. 7 is a perspective View of the outer end of an outer rib; and Fig. 8 is a transverse section of a part of the inner end of the body, showing the sinne on a larger scale. Fig. 9 is a seotionnl view of n. portion of the horn and bese showing more clearly the connection between the two end the ring rovided with the valve controlled openings.

ig. is a sectional'view of s, portion of the horn showing more clearl the manner of connecting the suspending oop thereto.

Corresponding and like parts nro referred to in the full-lowin description and indiouted in all the views o' the drawings by the saine reference .characters As indicated inost clearly in Fig. '1, the

horn comprises n body portion 1 and ii base 2, seid parts bein separable. The body 0f the horn is provi ed at its smaller end with a eollur 3 to which the base 2 is fitted by s slip joint. The base is provided with nn nir rliitinber 4 controlled by means of a, valve 5 for moderntingthe sound, the construction being substantially the seine as set forth in Patent No. 880,388, granted to ine Fobrusir)r 25,v 1908. 'llie contrai-.ted end ol' the nir cl'uiniber 4 (-.oiiiniiinieates with the smaller end of the body l, the letter having :in opening inits upper side and seid o inning being oovered by a hood 6 into whic the end of the air chamber 4 entends. The collar 3 is provided with n series oi' vzilve controlled openings 7 which admit of softening harsh sind unnatural tones.

rlhe body ofA the horn is eoinposed ol sections 8 of pressboard, inetsl or other suitable sheet materiel, said sections beine of u width, length and outline according to the size, design and finish of the horn when conn ileted.- The sevcriil sections are arranged with their longitudinal edges abutting and Arire connected b v ineens which result in u substantiel, nent and durable ioiiit. Slits or openings 9 are provided at intervals nlong the edge portions of the sootions S to receive the fastening ineens. Ribs or binding strips are placed upon opposite sides of the ioiiits foiined between the several sections. and

`these ribs ere deflected between their lungi tudinal edges to stiien the seine niid to ena-ble the edge portions to lit close against the parts ol' the sections clamped between them. The ribs or binding stripsconforin longitudinally to ii longitudinal ele-nient or seotion of the horn. Tho innerrib 'or strip 1l) is approximately of V-iorni in transverse section to correspond with the obtuse aiille forined between adjacent sections. e outer rib or section 11 in addition to having its odge portions deflected to eonform to the l :ingle formed between the outer feces of ed# jacent sections has its middle portionpressed outward in a substantially LLforni in cross ieetion, thereby providing a nest finish, as also supplyinf a rib having etaymg en sti'ening que ities. The outer end of the rib 11 is Het and is bent arouxid'the edge of the horn and over the outer end of the rib 10, as indicated at 12, and is soldered thereto. The inner end of the rib 10 is bent over the inner end of the rib 11, as indicated at 13. The inner end of the rib 11 is flat toenable the confining ring or band 14 fitting close against the contracted end of the horn. Prongs 15 project from the rib 11. and ass through the slits or openings 9 and are gent around the rib or strip 10, thereby securing the inner and the outer ribs or strips to the end portions of adjacent sections clamped between them. The prongs 15 may be provided in any manner and consist of legs or members of cli s or staples 16 soldered or otherwise attac ed to the rib 11, preferably to the inner side of said rib so as not to interiere with or obstruct'the appearance of the rib 11. After the several sections have been connected to complete the horn, the rin or band 14 is fitted to the lcontracted en 'of the horn and soldered or otherwise attached to the inner ends of the ribs. A ortion of the ring or band 14 projects beyon 4the contracted end of the horn so as to fit-about'the collar 3, to which it is soldered or otherwise firmly attached. The ring 14 simply provides a finish between the collar 3 and the inner end of the sections 8 and the ribs at the small end of the'horn.

The suspending loop 17 generally provided in connection with (phonograph horns has its` end portions passe through a section of the horn adjacent to contiguous ribs and the inner end portions of the loop are soldered or otherwise attached to the innerribs, thereby providing a substantial connection between said loop and the body of the horn. The hood 6 closin the opening by means of which the air ciamber 4 has connection with the inner end of the horn, is substantially of U-form in transverse section and its edge portions are soldered or otherwise secured to the inner ends of adjacent ribs.

In the event of the sections of the horn consisting of light pressboard or similar thin sheet material, the ribs in addition to'conneoting Vthe sections, provide substantial staying means for stiffening and bracing the horn and maintaining the shape thereof. The rib sections 10 and 11 are formed of stri s of metal clit into the required length an deflected between their longitudinal edges into the reuired shape substantially as herein s ecifie Havin t iis described the invention, what i and over-lap is claime as new is:

1. A horn of the character s eciied, comprisin a body and a base, t e two beingl separa le and ada ted to make connection i by means of a slip joint, the body of the horn ha a hooded opening near its inner end and t e base having a valve controiied air i chamber to make connection with the hood app 'ed to the horn body.

A horn of the character specified, provided at its contracted end with a series o valve controlled openin encircing the same.

3. A horn compos of sections, means forl connecting said sections, consisting of strips arranged upon o posits sides of the jomt forme between a jacent sections one of said strips havin prongs extended 't erefrom and passed t rough the sections 'and bent about the opposite strip.

4. A horn, comprising sections, strips laced upon opposite, sides of the joints ormecl between the sections, and clips attached to the outer strips and assed throu h the sections ci the horn and nt about t e opposin inner strips.

5. A orn ofthe characterdescribed, composed of sections, inner and outer strips arranged op ite the joints formed between the severa sections, said strips being deilected between their longitudinal edges to conform to the a le formed between adjacent sections,.an rongs -extended from one of the strips an passed uthrough the sections and bent about the opposite strips.

6. A horn of the character specified, coinposed 'o sections, inner and outer strips arranged op osito the joints formed between the .severa sections, the outer strips being deflected between their longitudinal edges and having their middlevportions ressed outward into an approximatel 'U- orm in cross section, and prongs exten ed from .the outer-strips and passed through the sections and bent about the inner strips to secure the several strips and sections together.

7. `A horn of the character described comprisin a series of sections, strips placed upon o posite sides of the joints formed between t e several sections and ha the opposite end extended and bent over t e ends of the sections and strips, and lprongs dprojected ronrone of the strips an y asse throu h the sections of the horn and nt about t e other strip.

8. A horn of the character specified comprising sections, strips connecting the several sections andA forming stiifening ribs, a collar at the small end o stri s attached thereto, and a vhand fitted to t e small end of the horn and the collar ing the joint formed between the sections and strips and the inner en s of the collar and secured said strips and to thecollar.
